As my switch adapted Tumbler car's now come in at £80, I wanted to find something to put in my shop that was a lot cheaper. I found these Chad Valley "Low Rides" R/C cars in UK Woolworths, which look great and are fairly easy to adapt for plug in switches. It's no where near as powerful and manic as the Hitari Tumblers, but at £25 it's a lot more affordable.
